DC-3A/B/C Marshall stability tester measures Marshall stability and flow of asphalt mixtures with digital force and displacement readout. Request a quote.
Overview
The Marshall stability tester is used to determine the Marshall stability and flow value of asphalt mixtures, and evaluate their high-temperature stability, deformation resistance and road performance. The instrument consists of a main frame, a loading system, a fixture, displacement and force sensors, an independent digital control box and a data processing unit. It is suitable for testing in road engineering, asphalt mixture production enterprises and laboratories.
Applications
• Hot mix asphalt (HMA) laboratory mix design and quality control
• Asphalt plant production monitoring and batch certification
• Road construction acceptance testing and pavement performance assessment
• Research institutions and highway engineering laboratories
Features
• Robust construction suitable for both laboratory and field use

FAQ
Q1: What standards does the DC-3A/B/C Marshall Stability Tester comply with?
A1: The DC-3A/B/C Marshall Stability Tester is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the DC-3A/B/C Marshall Stability Tester be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
